September 11th Families' Association

2,973 people were murdered by 19 terrorists during the attacks on Tuesday, September 11, 2001: 2,749 victims at the World Trade Center in New York and on American Airlines Flight 11 and United Airlines Flight 175; 184 people were murdered at the Pentagon and onboard American Airlines Flight 77; and 40 people were killed on United Airlines Flight 93.

Victims came from all over the world, particularly from the states of New York and New Jersey. Over 90 countries lost citizens in the attacks – actual counts by are nearly impossible, as many victims were born in one country, were residents of another and citizens of yet another.

Four victims have controversially been added to the list since 2007, one by court order and three by the Office of the Medical Examiner, bringing the official total victim number to 2,977 as of June 17, 2011.

Of the 21,812 remains (174 intact bodies, the rest partial remains) recovered in New York City, 12,792 (59%) have been identified as of May 3, 2011. A total of 9,022 remains (or 41%) have not yet been identified. Fifty-nine percent or 1,627 victims of the attack have been identified as of May 3, 2011; leaving 1,122 victims (49%) unidentified.

All the victims of United Flight 93 have been identified. Of the Pentagon and Flight 77 victims, 179 have been identified; 5 have not.

As of late 2009, thousands of illnesses and 817 deaths among World Trade Center recovery workers had been recorded. Most of these people were under 50 at the time of their deaths and had no health problems before working at the recovery. Very few studies have been done thus far on the health effects of working at the World Trade Center site, so proof as to the official cause of their deaths is unavailable. It is estimated that over 400,000 people were exposed to the toxins at the World Trade Center site. New York City is tracking the respiratory issues of approximately 71,000 of these people.
